From Kanye West's 'stand up' to Barbra Streisand's medley with Fallon

If it's a trend, a clip, a comment, a moment, a meme, a tag, or a topic, it's a thing. Thing Tank is a review of the week in things, and rates them either up or down.

HAVE A SEAT

Actually, don't you dare, especially at a Kanye West concert. The rapper stopped his concert in Sydney last week until everyone was standing up. But, um, what about that guy in a wheelchair? 'This is the longest I've had to wait to do a song,' West huffed in a video that circulated far and wide. After a bodyguard verified the wheelchair claim, West went on with the show - and the Kanye haters went wild.

TWEET THAT

A welcome reminder of social media's power to do good, two Twitter users helped Philadelphia police track down a group who allegedly attacked two gay men on Sept. 11.

One user posted images of the suspects and matched them to a Facebook photo of a party at a nearby restaurant.

Another user identified the restaurant and used Facebook's 'check-in' feature to confirm the suspects had been there.

'This is how Twitter is supposed to work for cops,' Philly detective Joseph Murray tweeted.

This is how Twitter is supposed to work for cops. I will take a couple thousand Twitter detectives over any one real detective any day.

A clever PR stunt mutated into a colossal misfire when U2's new album, 'Songs of Innocence,' magically showed up for free on iTunes users' phones and in their music libraries. Just one problem: Not everyone wanted it. (Google Tyler the Creator's hilarious string of F-bomb-laden tweets about the situation.) It forced Apple to release instructions on how to delete the album.

BLOOD ON THEIR HANDS

Charmless @UrbanOutfitters exploits police murder for some 'radical chic'. Immoral and tasteless.#KentState http://ift.tt/1rcr38C

Knock, knock. Is anyone home in Urban Outfitters' marketing department? The clothing company came under fire when it advertised a 'vintage' Kent State University sweatshirt splattered with what appeared to be blood. Aww, cute: A reference to that time four unarmed Kent State students were killed at a campus protest in 1970. Even more offensive? It listed for $129 - before the company yanked it offline.

HELLO, GORGEOUS

For the first time in more than 50 years, Barbra Streisand returned to late-night television as a guest on 'The Tonight Show Starring Jimmy Fallon.' Promoting her new album, 'Partners,' the funny girl enlisted Fallon to perform a medley, with Fallon singing the parts of Elvis Presley, Blake Shelton, and Michael Bublé. Streisand's critique of Fallon's singing? 'I wouldn't give up your night job.' And her own voice? Like buttah.
